Video: Falcon 9 hot fire

Launch of a SpaceX Falcon 9 rocket carrying a Dragon cargo ship loaded with more than 5,100 pounds of equipment and supplies bound for the International Space Station was called off Tuesday less than two minutes before liftoff because of apparent problems with the second stage engine steering system.

The mission comes as SpaceX continues to ferry four astronauts to the International Space Station on Axiom Mission 4, which launched in the predawn hours. Liftoff occurred from pad 40 at 3:54 p.m. EDT (1954 UTC).

Powering off the planet just after sunset Friday, a SpaceX Falcon 9 rocket took off from Cape Canaveral with the multi-mission SES 9 communications satellite to link millions of homes, businesses, ships and airplanes across the Asia-Pacific.
